i'Be lit :known that: I, yJAMES -MADIsoN `.GIL- -\BERT,- ba :citizen :of theli United States residing at Dallas, intthe'countyof DallasiandaState fofllexas, have inventedA certain .new.and Vuse- .iiulf Improvements .in Gatesgzand I =do declare the following to be a full, clear,.and exact -de- .-scription of- `the invention, such vas will enable and nut 12.

fothersi'slrilled in. therart :to -which itvapperto :make andiuse .thesame i This invention Irelates to f gates; and one 4of athe, 'principal @objects of: the :same is to: .rpro- -svidera1gate=which may be openedeitherout-i Ward or inward by the occupants'ofa vehicle :uponiapproachiing the same-.without the necessit-y ofv-aliglhtfing from the vehicle, :means being provided whereby the latch for secu ning? the gate inza closed position will vbe released by the initial movement 'of the `gate-operating mechanism.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a gate constructed in accordance with my invention, the gate being shown in closed position. Fig; 2 is a side elevation of the gate and its operating mechanism, parts of the latter being shown in vertical section. Fig. 3 is a detail horizontal section of the gate, the operating mechanism, and the hinge-post; and Fig. 4. is a detail vertical sectional view through the upper end of .the gate-operating mechanism and the support1ng-bracket of the same and taken at right angles to the section shown in Fig. 2.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the hingepost, and 2 the latch-post, of the gate. The gate 3 may be of any suitable construction, but is here shown as consisting of longitudinal horizontally-disposed bars 4, connected at their ends by the upright bars 5. Bolted to the hingepost 1 are a pair of laterally-projecting brackets 6. In the upper supporting-bracket is secured a vertically-disposed bearing 7, which projects through the bracket and is adjustable therein by means of the bolt and nut 9. In the lower bracket a similar bearing 1() is provided and is also adjustable by means of the bolt 1 1 These bearings are each provided with a conical recess 13, and mounted between these bearings is a shaft 14, having an l\with two spirally-:arranged grooves 21'6.

Connected'v to.y the .'beating-block,21':is-a connecting-rod 23, ex-

i tending ina-n iinolinedl lZd'irection .downward .and :having vits lower end pivotally:connected to a crank 24,|said crank :beinganounted upon a shaft.25, which ,passes througha .longitudif-nal bar of the` gate. Upon the oppositefend of said shafta .disk 26 ,andi a pla te26 are mounted -andiat the vo p.posite-ends of said plate pins 27 project outward therefrom.

The latch 28 of the gate is pivoted upon a bolt 29, said latch comprising a long bar or rod which extends over the pins 27, the outer end of said latch-bar being adapted to engage a keeper 30, said keeper being secured to the latch-post 2 and provided with the inclined portions 31. To limit the movement of the latch-bar a bail 33 is secured to one of the uprights 5.

The operation of my invention may be described as follows: To open the gate, one of the levers 22 is pulled downwardly, which movement will draw upwardly upon the operating-rods 19, thus moving the collar and causing the lugs to rotate the sprially-grooved portion, and thus open the gate, the latch being operated by the movement of the connecting-rod, the crank and the plate provided with pins for raising the latch-bar out of the keeper. To swing the gate in the opposite direction, the lever 22 is pushed upwardly. It will thus be obvious that the gate can be swung in either direction outward or inward past the latch-post. However, it will be noted that the latch-bar will always engage the keeper when the gate is in line with said latch-post.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without re uiring a more extended explanation.

arious changes in the form, proportion, and the minor details of construction may be IIO resorted to without departing from the principle or sacrificing any of the advantages of this invention.

I-Iaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isd

l. In a gate, the combination with a hingepost, of supporting-brackets secured thereon, a spirally-grooved shaft mounted to rotate between said brackets, a collar engaging theI `grooves 1n said shaft, operating-rods conmeans for raising and lowering the operatingrods and a latch to be moved simultaneously with the swinging of the gateby means sub- Y stantially as described.

3. In a gate, a spirally-grooved shaft connected to the gate, a collar connected to said 'grooved shaft by means of lugs projecting into the grooves, sliding rods connected to the collar, a latch, and means connected to the operating-rods for raising the latch out of its keeper' at the initial movement in swinging the gate.

4. In a gate ofthe character described, the combination with a hinge-post and a latchpost, of upper and lower supporting-brackets secured to said hinge-post, up er and lower bearings adjustable within said brackets, a spirally-grooved shaft mounted in said brackets, a collar mounted to slide on said grooved shaft, operating-rods connected to said collar, means for moving said operatingrods, and a latch movable by connections between the operating-rods and the latch, substantially as described.

5. In a gate, a spirally-grooved shaft coni nected to said gate, reciprocating rods carrying a collar for rotating said grooved shaft, means for reciprocating said rods, and a latch adapted to be raised out of its keeper by the initial moveinentof said rods, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
